SPRAYING PEACHES WITH AESENICALS. 
209 
the fruit was infested. Nevertheless, the results show a certain 
benefit, there being a gain in uninjured fruit on the plat treated with 
arsenate of lead of 20.63 per cent, and on Plat II, treated with lime, 
of 10.76 per cent. 
Results obtained also in 1906 at Myrtle, Ga., are shown in Table 
CIII. The trees treated were located in an 8-acre block of the 
Georgia Belle variety, composing a 200-acre orchard. The treated 
area, however, was on one side of the orchard and fairly well separated 
from the main body of the trees. Conditions for the curculio were 
here ideal on account of adjacent woods, and the presence here and 
there through the orchard of terraces which had become overgrown 
with bushes, weeds, etc. Each plat comprised 50 trees. The dates 
and character of applications are shown in the table, as well as the 
number of trees on which records were taken. 
The average percentage of sound fruit on the untreated trees was 
67.59 per cent. As compared with this injury there is a gain in 
sound fruit on Plat I, sprayed with arsenate of lead, of 21.04 per cent, 
and on Plat II, sprayed with lime, of 2.20 per cent. 
Results of spraying peaches at Mayfield, Ga., for the curculio in 
1 908 are shown in Table CIV. This work was carried out by the office 
of the Georgia State entomologist according to a plan furnished by 
this bureau. Each plat contained 60 trees of the Elbert a variety, 
and while a sufficient number of trees was not used for making counts 
of the fruit, the results are nevertheless significant.
